Thanks for the update. I will try them in the morning. They are normally my first choice. the guys at Clays Ace and the Downtown Ace just looked at me with funny looks wondering what I was talking about.

CD Fasteners has 1/4″-20 eye nuts in stock. I’ve bought all of mine from them. They aren’t stainless but should be more than sufficient enough for rocketry use.Edward

Awesome!Its on its way to you as a PM and as an email…

With smart phones like the Droid (since that did work), this should be easy to do with a bulk phone text message to all local members.I need to obtain a list of all cell phone numbers of those who want…   Read more»

With the ability to use T-mobile and Verizon 3G at both sites and with Droid phones, (that is what I have so I am familiar with its capabilities) I guess we could log on to this site from our phones…   Read more»

Yeah, I did the same thing about 30 minutes after you did. With all the hams in the club now, we should figure out a frequency we can give regular launch updates on while people are driving in. Better yet,…   Read more»

Wow, I also bought a Telemetrum. It’s a great product. I kept hoping that Jim Amos would finish his MPAC (not sure of spelling) system, but I think that will probably never happen.We’re going to need a club flag system…   Read more»

Shunt 1, Yes, you would have been allowed to launch – we would have simply indicated on the paperwork “Number Pending”. Most of the time, folks can’t get away without being a member for long. This rocketry family takes care…   Read more»

Great news:I registered as a member of Tripoli and was almost in a panic this morning, since I still had not received my official TRA number for my Level 1 certification attempt. My emails were being ignored.Finally today, I received…   Read more»

Help me catch the Fox that is often in my back yard and we can attach one of your trackers to it! LOLSend by private email more information about using my Droid phone.My rocket may “only” reach 9,000 ft but…   Read more»

If you have a droid phone I know you can download software so that you can track radio signal locations and use your phone to help track, if you are on the 2 meter APRS frequencies, and since, Verizon and…   Read more»

I can fully blame my choice of GPS tracking all upon Adrian!BEAR, you never told me that you already had a Telemetrum that I could test drive. Oh well…As for the Ham written test:This is how I learned all about…   Read more»

I purchased a subscription to http://www.hamtestonline.com You can change your training around to fit your needs, but it gave me every test question there was, let me study the questions and the back ground reasoning for doing so, learned a…   Read more»

I was up past midnight trying to get my rockets ready for this launch. Still not ready, so I got up bright and early to do silly things like mount the altimeter.Watching the winds around the Atlas site all evening,…   Read more»

Well if you will be working the next launch, I guess I will volunteer right now to tow both ways.

Actually, Mike, I don’t think you will have to recertify. NAR and TRA have agreements where they honor each other’s certs. So, all you have to do is maybe fax them a copy of your TRA card showing L2 cert,…   Read more»

Doug is right, the main difference would be the amount of epoxy forced out of the fabric into the breather material or sucked into the epoxy trap if you use one. Lower vacuum pressure reduces the compression on the layers…   Read more»

how much real difference is there in the final product if you go from say 10″ to 20″ of vacuum?Not that much. As you pointed out normally I draw as much vacuum as I can. However, there have been cases…   Read more»

The chief issue is our altitude here. That limits the maximum amount of vacuum you can pull. At my altitude (7000′), I can get just a hair over 26″ of Hg on the vacuum gauge when I get everything really…   Read more»

Go for it. I will be BU. I will PM my phone number.
